Now that we've moved into Daylight Saving Time (DST), let's look at how EZWxBrief provides help with time zones for the route you are planning. For more information on how to set your time preferences you can reference this post. And in this EZTip, you can see how those time preferences are rendered in the progressive web app. But what about a proposed route that crosses time zones?
Let's say you are physically located in the eastern time zone (your local device time) and you are planning a flight using EZWxBrief from Charlotte, North Carolina to Memphis, Tennessee which crosses from the eastern time zone into the central time zone. At the bottom of the EZRoute Profile you will see a line containing the accumulated distance and below that, the estimated time of arrival at each segment point along the proposed route of flight. The time format shown here is based on your specific settings/preferences for time (in this case Zulu is the preference). The first time on the left at the departure airport is your time of departure (always at the top of the hour) based on the time set on the EZDeparture Advisor.
From there, you will notice that if you hover over the estimated time of arrival row, that a popup appears (tap on this for a portable device) at the segment point of interest. Any segment point that occurs within your time zone will have both the Zulu time and local time for that arrival in that tabular display. In the example above, the arrival time at the third segment point (magenta circle) is 1731Z or 1:31 PM EDT.
The flight crosses over to the central time zone between KMNV and KCSV. Therefore, hovering over the arrival time at 1833Z (immediately below KCSV) EZWxBrief now shows you the local time of 2:33 PM EDT (based on the device time), 1833Z and 1:33 CDT (see below).
